| Abstract Scope |
In this paper, Originated from Ti(Bu)4，nano-rutile Sn-TiO<SUB>2</SUB> was synthesized by low temperature hydrolytic process. Then they were characterized by means of X-ray diffratction，UV-vis diffuse reflectance，fluorescence spectrum.Results showed that with the increase of the doped concentration of Sn，the reflectance of DRS decreased accordingly，while the powder’s increase in light absorbance. Absorption of light broad to the visible region. which indicated that red shift occurred. the fluorescence spectrum intensity of Sn-TiO<SUB>2</SUB> increased according to the doped concentration，Sn-TiO<SUB>2</SUB> change the crystalline form when Calcined at different temperatures: in the low temperature for anatase; as the temperature rising, it transist to rutile ,while at 800 ℃ ,it is almost entirely rutile. with the increase of the calcination temperature, the Absorption of DRS increased , while the fluorescence spectrum intensity of Sn-TiO<SUB>2</SUB> decreased accordingly |
